The A20PB-04RS external
power supply and the I/O
module power supply are
shared.

Because mounting hole size is
different, reworking is
required.
Mounted to DIN rail
Mounted to DIN rail
The A20SB-04US and
A20PB-04RS can be mounted
to the existing DIN rail.
Be careful about the mounting
dimensions as two modules
are required.
